Raiders TE David Ausberry to have knee surgery

NAPA, Calif. -- Oakland Raiders projected starting tight end David Ausberry is scheduled to have knee surgery and will miss Friday's preseason opener against Minnesota.

Ausberry has not practiced this week and did not attend Tuesday's workout as a spectator, like the rest of Oakland's injured players. Coach Dennis Allen was tightlipped when discussing the issue and didn't disclose the exact nature of the injury or what knee Ausberry hurt.

A seventh-round draft pick, Ausberry missed all of 2013 after suffering a serious shoulder injury during the Raiders second preseason game in New Orleans. He later underwent surgery and was placed on season-ending injured reserve.

Despite that, Ausberry was listed as Oakland's starter when the team released the first depth chart of camp.
